What makes the Fingal scheme different

Fingal County Council operates the oldest unchanged differential rent scheme in the Dublin region.

The 12% flat rate, no disregard, no child deduction model has been in place since April 2013, and a proposed increase to 14.5% was approved by the executive in November 2025 but paused by elected members and remains under review.

The practical impact of the flat-rate design is that a Fingal tenant on €350 a week pays €42, while the same household under the new Dublin City rate would pay around €53 once the €55 disregard is applied.

Fingal is therefore the cheapest of the four Dublin local authorities for households between roughly €200 and €600 weekly income.

Above €600 the lack of any cap or graduated band means rent rises in a straight line, and a tenant on €900 a week pays €108, the same as a household on €750 a week in Dublin City.

The €40 subsidiary cap matches Dublin City, but unlike Dublin City the absence of any disregard means every euro of subsidiary income contributes from the first euro.

If the 2026 review passes the proposed 14.5% rate, a single earner on €400 a week would see weekly rent move from €48 to €58, a €520 annual increase, and the council has indicated transitional protection for the lowest-income tenancies.

How Fingal's differential rent scheme works

12% flat rate of assessable income with no threshold or disregard. Minimum rent €22/week. No child deductions. Subsidiary earners pay 12% capped at €40/week. A proposed increase to 14.5% was approved in November 2025 but paused by councillors and is pending review in 2026.

What a Fingal tenant would pay at different income levels

Calculated from Fingal's published scheme rules above, for a single tenant with no dependants. Your actual rent depends on household composition, dependants, subsidiary earners, and any allowable deductions.

What to bring to a Fingal rent review

Fingal typically reviews differential rent annually, and any change in household composition or income should be reported to the housing section within 14 days of the change. The documentation required is broadly the same as other Irish local authorities, with a few Fingal-specific points worth knowing in advance.

Understanding the Fingal differential rent scheme in detail

Differential rent is the system every Irish local authority uses to set rent for social housing tenancies, where the weekly amount you pay is tied to your household income rather than to the open-market value of the home.

The legal foundation sits in Section 31 of the Housing (Miscellaneous Provisions) Act 2009, which gives each of the 31 local authorities the power to design and publish its own differential rent scheme.

The result is that the rent paid by two households with identical incomes can differ from one council area to another, sometimes by tens of euro a week, because the rate applied, the income disregard allowed, the way subsidiary earners are treated, and the minimum and maximum weekly rent are all set locally.

The Fingal County Council scheme summarised on this page reflects the rules currently in force and last reviewed in April 2013.

Under the Fingal scheme, the primary earner in a household contributes 12.0% of their assessable income each week toward rent.

The minimum weekly rent is set at €22.00, which is the figure most households on Jobseeker's Allowance, the State Pension, or Disability Allowance will land on once their assessable income, dependants, and any allowable deductions have been factored in.

The maximum weekly rent is uncapped, which means rent continues to climb in line with income with no upper limit.

Assessable income is one of the most misunderstood terms in social housing, and it is worth pausing on.

Fingal, like every Irish local authority, counts gross wages, salary, and self-employment earnings, together with the bulk of social welfare payments — Jobseeker's Allowance, One-Parent Family Payment, Disability Allowance, Carer's Allowance, the State Pension (Contributory and Non-Contributory), Invalidity Pension, Widow's or Widower's Pension, Working Family Payment, and similar weekly schemes.

Maintenance payments received under a court order are included. Rental income from a sublet, a room let, or a second property is included.

What is excluded varies but typically covers Child Benefit (Children's Allowance), the Fuel Allowance in many cases, the Domiciliary Care Allowance, certain Foster Care Allowances, and the Living Alone Allowance where applicable.

Some councils disregard the first portion of Working Family Payment, and some give a partial disregard for income earned through Community Employment schemes; Fingal publishes a definitive list which should be consulted before submitting an income review.

Household composition matters as much as income. The principal earner — usually the tenant of record — is assessed at the full primary rate.

Any additional adult in the household who earns is treated as a subsidiary earner, and this is where schemes diverge most sharply across the 31 councils. Fingal charges subsidiary earners at 12.00% of their income, and the contribution from each subsidiary earner is capped at €40.00 a week.

The percentage model scales with ability to pay and is generally fairer than a flat charge, but it requires every earner in the household to be assessed individually.

Either way, a household that takes in a working lodger, a returning adult child, or a partner who starts a new job is required to inform Fingal in writing, usually within 14 days, so the rent can be recalculated.

Dependent children reduce the assessable income figure. The current Fingal scheme does not include a per-child deduction; instead, the rates and disregards are calibrated to deliver a comparable outcome for households of different sizes.

If your circumstances have changed because a child has been born, has left full-time education, or has become a registered subsidiary earner, contact the housing section so the file can be reviewed.

Where a deduction applies it is taken off the assessable income figure before the percentage rate is calculated, not off the final rent — a subtlety that becomes important when comparing your council letter against the indicative figures in the table further up this page.

Rent reviews are an annual or biennial fixture in every Irish local authority and Fingal is no exception. The review typically asks tenants to submit recent payslips, social welfare receipts, P60s or end-of-year statements, and any documentation relating to changes in household composition.

Where income has risen since the last review the new rent applies from a specified date, usually the start of the next rent week.

Where income has fallen — for example, after redundancy, the end of Working Family Payment, or the birth of a child — the tenant should request an interim review rather than waiting for the annual cycle; the recalculated rent applies from the date Fingal receives the documentation, not from the date income changed, so prompt notification matters.

Failure to declare a change in circumstance can result in retrospective arrears and, in serious cases, tenancy enforcement.

It is also worth understanding how differential rent fits alongside the other housing supports administered by Fingal.

The Housing Assistance Payment (HAP) is the primary scheme used when a household qualifies for social housing support but is housed in the private rental market; the council pays HAP to the landlord and the household pays a differential rent contribution to the council, calculated using the same rules as council-owned tenancies.

The Rental Accommodation Scheme (RAS) is a longer-term contractual model with private landlords that also uses differential rent for the tenant contribution.

Cost rental, by contrast, is a separate scheme entirely — rent is set as a function of the building's cost, not the household's income, and is delivered primarily through Approved Housing Bodies and the Land Development Agency rather than through the council's general housing stock.

The figures generated by this calculator apply to council and HAP tenancies; cost-rental rents follow a different methodology and are covered on our cost-rental calculator page.

Finally, a note on accuracy. The figures shown in the indicative table and produced by the calculator are estimates calibrated to the published scheme rules.

They are useful for planning — for understanding how a pay rise, a new household member, or a change in welfare payments will affect rent, or for comparing what a household would pay across different council areas.

They are not a substitute for the official rent letter issued by Fingal, which incorporates any local discretion, transitional arrangements, or specific deductions that apply to your tenancy.

If the figure produced here diverges significantly from your council letter, the council letter is correct and the most common reason for divergence is an income source, deduction, or household member that the calculator was not told about.

The housing officer at Fingal can talk you through how the figure was arrived at line by line, and any tenant has the right to request that breakdown in writing.
